Abstract
Abstract This invention relates to a dye receptor element for thermal dye transfer which comprises a support having thereon a resinous binder consisting of chlorinated polyvinyl chloride or chlorinated polyvinyl chloride with other resinous blends. Dyes which are transferred to the dye receptor sheet have good solubility in the dye receptor sheet, and achieve high dye densities in the dye image.
